How it works

Three steps from draft invoice to money in your Square account.

Build the invoice

Add customers, line items from your catalog, net terms (5, 7, 10, or 20 days), and your logo. Each workspace keeps its own contacts and products.

Send from Gmail

Deliver invoices from the Gmail address your customers already know. PDFs and logos can live in your Google Drive — we only access files the app creates.

Collect payment

Customers open a branded pay page, pay by card or bank through Square, and optionally save a method for auto-charge on the due date.

Everything you need, nothing you don’t

Built for freelancers and small businesses who want invoicing that feels as straightforward as sending an email.

Your Square account

Each workspace connects its own Square seller account. Payments go to the merchant who sent the invoice — not a shared platform wallet.

Your Gmail identity

Invoices arrive from your address, so customers trust who they’re paying. Connect Gmail and Drive once per workspace.

Net terms & auto-charge

Set due dates with standard net terms. Optionally save a payment method and auto-charge when the invoice comes due.

Product catalog sync

Pull items from Square so line entries stay consistent. Add one-off items manually when you need to.

Separate workspaces

Run multiple businesses or teams under one login. Billing, branding, and integrations stay isolated per workspace.

Card & bank on one page

A single branded pay page handles card and ACH. No redirect maze — customers pay and you get a clear paid status.
